nollapituusviitteitä
Nollapituusviitteitä refers to a concept used primarily in the fields of geometry, physics, and engineering to denote references or measurements that have zero length. The term is derived from Finnish, where "nolla" means zero, "pituus" means length, and "viitteitä" translates to references or pointers. In practice, a nollapituusviite is a reference point or vector that does not extend in any direction, effectively representing the origin of a coordinate system or a baseline against which other lengths are measured.
The use of zero-length references is common in analytical geometry, where coordinate axes are defined to intersect
In engineering design, zero-length references are employed when specifying tolerances or constraints relative to a datum
Because these references have no physical size, they are immune to dimensional changes in manufacturing or
